Hereinafter, with reference to the drawings, the nature-friendly slope greening construction method and structure using the vegetation wire mesh basket according to the present invention will be described in detail with reference to the embodiment.

The nature-friendly slope greening construction method using the vegetation wire mesh basket according to the present invention can satisfy both the disaster prevention effect and ecological restoration by using the vegetation wire mesh basket to construct multi-layered greening in a cascading way on an incision in a river or a relatively steep slope. It relates to a nature-friendly greening construction method that has a natural greening construction method, and with reference to FIG. 1a , slope clearing and topsoil acquisition step (S10), vegetation wire mesh basket installation step (S20), rock layer formation step (S30), soil layer formation step (S40), cover soil layer formation Step (S45), seed sowing step (S50), soil backfilling step (S60) and repeated implementation step (S70) may be included.

The slope clean-up and topsoil acquisition step (S10) performs the basic ground clearance work to clean the ground of the slope such as rivers, but after cleaning the ground, the foundation (B) is prepared with gabions or filling stones, and it may be constructed on it , if necessary, mobilize heavy equipment such as fork cranes and bulldozers to excavate the ground, and arrange the ground located on the side of the river to become a sloping slope (S) having the necessary angle for slope construction. Topsoil is generated at the site during slope cleanup work, and in the present invention, such topsoil is stored and then used by covering the soil layer 400 .

The vegetation wire mesh basket installation step (S20) is a process of arranging a plurality of vegetation wire mesh baskets 100 made of a metal mesh on the slope S in a horizontal direction so as to be adjacent to each other and connecting them to each other.

Referring to FIG. 2 , the vegetation wire mesh basket 100 is a substantially hexahedral-shaped enclosure made by weaving wire meshes having a plurality of mesh nets. The front cover 110, the rear wire mesh 120, the side wire meshes 130 on both sides. , the bottom wire mesh 140 and the upper cover 150 are connected to each other to form an accommodating space therein, and may be arranged in a stepwise arrangement along the slope of the slope S to form a structure as shown in FIG. 4 .

Referring to Figure 4, the vegetation wire mesh basket 100 is firmly fixed in the horizontal direction to the slope (S) or the backfill layer with the rear wire mesh 120 as a horizontal nail 125, thereby vegetation by the load of rocks or soil. Prevent the wire mesh basket 100 from being separated or disturbed individually.

The vegetation wire mesh basket 100 has a rock mesh 160 formed on the inside to accommodate and support the rocks, thereby preventing soil or plants from being pushed out between the holes of the vegetation wire mesh basket 100 by the pressure of the rock.

At this time, the rock mesh 160 is formed in the lower rear portion of the accommodating space inside the vegetation wire mesh basket 100 to prevent the load of the vegetation wire mesh basket 100 from being tilted or tilted forward, and the rock mesh 160 is formed on both sides. While coupled to the wire mesh 130 and spaced apart from the bottom wire mesh 140, the rock vertical mesh 161 installed in the vertical direction upward, and the rock vertical mesh 161 are coupled to the upper part to close the rock mesh 160 A rock filling space in which the rock is filled is formed by the rock cover 162 .

In addition, the soil filling space 170 is formed in an approximately "┌" shape in the front and upper sides of the rock mesh 160, and soil is filled therein.

Referring to FIG. 3A as an example, the blocking sheet 180 is installed in the vertical direction on the rear wire mesh 120 of the vegetation wire mesh basket 100 to prevent the inflow of soil from the backfill layer 700 and the slope S. have. The blocking sheet 180 includes a base layer (not shown) made of high-density polyethylene, an upper coating layer (not shown) and a lower coating layer (not shown) made of low-density polyethylene on top and bottom of the base layer, an upper coating layer and a base layer Alternatively, it is interposed between the lower coating layer and the base layer to include a grid layer (not shown) that is made of a mesh of a metal material and provides strength.

As such, the base layer is made of high-density polyethylene and has a high strength due to its dense molecular structure and blocks moisture. can be prevented In addition, by combining the upper and lower coating layers made of low-density polyethylene on the upper and lower parts of the base layer to provide elasticity and elasticity to the floor sheet 200, it acts flexibly by external loads such as earth pressure and water pressure of the slope (S) ground, making it easy to operate. It is not damaged, it is not easily cracked, and it has moisture-proof properties, so it can triple block the inflow of excessive moisture from the ground of the slope (S) in case of rain. In addition, a grid layer made of a metal material having a grid shape is interposed between the base layer and the upper and lower covering layers to increase the strength of the blocking sheet 180 to support the load of rocks and soil on the slope (S) ground. Accordingly, the soil of the slope ground (S) is prevented from subsidence or loss, and the slope (S) can be collapsed or maintained in the original shape of the vegetation wire mesh basket 100 constructed by external pressure.

In addition, the moisture storage unit 200 is formed in the lower portion of the vegetation wire mesh basket 100 is fixed. The water storage unit 200 may be made of synthetic resin, and is a kind of container that has an open upper side to store water such as rainwater in the inner water storage space to block external leakage, and a soil moisturizer ( 210) is installed.

Conventionally, there was a problem in that the water content was low and the water storage effect was not large due to the low porosity because the drainage part was formed inside the vegetation wire mesh basket and the drainage part was filled with a mixture of soil, rocks, and aggregates. In addition, in the prior art, the vegetation cloth installed in the front of the vegetation wire mesh basket was to absorb the water from the drip tray to supply moisture, but only the moisture in the front part of the vegetation wire mesh basket can be absorbed limitedly, and the amount of absorption is insignificant, and only a small part of the front part of the vegetation wire mesh basket. There was a problem in that only the soil was supplied with moisture, which did not greatly help the germination and establishment of seeds.

However, in the present invention, the moisture storage unit 200 blocks moisture such as rainwater flowing into the moisture storage space from leaking to the outside, and moisture is absorbed through the soil moisturizer 210 having a moisture storage function, resulting in a high moisture content. It can be stored, and moisture can be uniformly supplied to the entire soil layer 400 filled in the soil filling space 170 through the filling material 310 filled in the rock layer 300 .

The soil humectant 220 that is put into the moisture storage space of the moisture storage unit 200, stores moisture and then discharges it, supports the load of the upper rock layer 300 and the soil layer 400, and stores a lot of moisture through the pores. It is sufficient as long as it is a material that makes it possible, but sand with finer particles than the soil constituting the soil layer 400 is also possible. The particle size of the soil constituting the may be 0.1 to 1 mm, and since the particle size of the soil moisturizer 220 is relatively uniform than that of the soil layer 400 having a large particle size as the particle size is fine, the porosity is large and the moisture is stored as much as possible. The available space will also increase.

In another embodiment, the soil humectant is 30 to 40% terracottam by weight, 20 to 30% zeolite, 10 to 20% attapulgite, 10 to 20% phyllite powder, 5 to 10% humus, and 5 to 10% liquid manure. may include

The Terracottem is a representative soil moisturizer, and is a mixture of materials such as a water absorption polymer, a nutrient element, a growth promoter, and an electrolyte, and can store moisture up to several times its own weight. It can be gradually fed into the roots of plants. At this time, the terra cotem is preferably included in the range of 30 to 40% by weight, because when excessively included, the soil may swell.

The zeolite serves as an adsorbent as a porous inorganic material. This serves to absorb moisture, store it, and discharge it to the outside, and it is preferable to add 20 to 30% by weight, and if it is less than 20% by weight, the moisturizing effect may be weak, and if it exceeds 30% by weight, soil and soil because it may swell.

The attapulgite is microcrystalline, has a tunnel structure by a silicic acid tetrahedral chain structure, and is a light and porous ultrafine clay mineral. It has excellent bonding to humus, etc., and excellent absorbency, so it can absorb moisture and store it inside.

The phyllite powder contains a lot of sulfur, and since it contains trace elements such as manganese, copper, zinc, iron and molybdenum, 10 to 20% by weight is included in the present invention to plant and soil various inorganic salts. However, if it is excessively included, the water content may decrease.

The humus soil is soil produced by decaying and decomposing leaves or small branches by microorganisms, and because it is very porous, it has good drainage and has excellent moisture and nutrient retention. It can provide both moisture and nutrients.

The liquid fertilizer is prepared in a liquid form by diluting the fertilizer in powder or particle form, and is a nutrient source for microorganisms necessary for the soil, improves the soil by preventing acidification of the soil, and can improve stamina, for this purpose, 5 to 10 weight % may be included.

The rock layer forming step (S30) is a process of stably reinforcing and protecting the slope S by filling the rock filling space of the rock mesh 160 of the vegetation wire mesh basket 100 with rocks to form the rock layer 300. At this time, the rock layer 300 may be about 1/2 times the total height of the vegetation wire mesh basket 100 .

That is, in the state in which the upper cover 150 of the vegetation wire mesh basket 100 is opened, the rock mesh 160 is filled with rocks to form the rock layer 300 , and the filling material 310 is put into the rock layer 300 and the filling material The function of supplying moisture and nutrients from the water storage unit 200 to the soil and plants of the soil layer 400 while the 310 fills the space between the rocks and the rocks so that the rocks do not flow and settle stably, and By preventing the soil from flowing out or subsidence of the soil layer 400 , the vegetation wire mesh basket 100 can be continuously maintained in its original form. When the construction of the filler 310 is finished, the rock cover 162 is covered on the upper portion of the rock layer 300 to support the rock layer 300 so as not to be tilted to one side.

The filler 310 is supplied with moisture from the moisture storage unit 200 to the soil layer 400 until the seeds sown in the soil layer 400 germinate and become established and the roots extend into the soil to some extent and grow. When the root extends further and extends into the space between the rocks of the rock layer 300 , it is possible to naturally absorb the moisture of the moisture storage unit 200 .

At this time, the filler 310 is 40 to 60% of earth and sand, 15 to 25% of perlite, 10 to 20% of cotton fiber or rayon fiber, 5 to 10% of diatomaceous earth and 5 to 10% of vegetable adhesive by weight%. .

The soil can be used in the vicinity of the construction site, has a particle size that can fill the gaps between rocks, and contains 40 to 60% by weight so that the roots of plants extend to the soil and absorb moisture and nutrients.

The perlite is a fine particle formed by pulverizing perlite, foaming and expanding, and it is made of a porous material with many micropores and a large surface area, and contains 15 to 25% by weight and has a particle size of 0.01 to 0.02mm, so the gap between the rocks that are not filled with soil to increase the cohesiveness between the rocks, move moisture through the micropores so that it can be stored in the moisture storage unit 200, and act as an alkali to suppress the loss of alkalinity of the soil, thereby delaying neutralization.

The cotton fiber is a natural vegetable fiber with a length of 40 to 60 mm and a thickness of 10 to 20 μm, and it is preferable to use a thin and long form. It has excellent hygroscopicity and there is a passage where water and nutrients moved, so moisture can be absorbed and moved. It is preferable to use it after making it.

The rayon fiber is an abbreviation of viscose rayon fiber, it has a long and thin form, and it is preferable to use a thing having a length of 40 to 60 mm and a thickness of 10 to 20 μm. Likewise, it has excellent hygroscopicity, so it can store moisture or absorb moisture and deliver it.

In this way, 10 to 20% by weight of the cotton fibers or rayon fibers of the elongated form are evenly laid in various directions, overlapping or adjacent to each other. 200) or absorbs and stores moisture by itself, and when the soil layer 400 lacks moisture, the moisture stored in the moisture storage unit 200 or the moisture stored by itself is permeated into the soil layer 400 and provided to plants It can also penetrate through small cracks between rocks.

The diatomaceous earth is a sediment produced by the accumulation of siliceous toxin of diatom, a single-celled alga, on the sea or lake bottom. The gap between the rocks is increased to increase the cohesiveness between the rocks, and the moisture moves through the fine pores to be stored in the moisture storage unit 200 .

The vegetable adhesive is an adhesive prepared by heating and stirring rice powder, corn powder, soybean powder, etc. with water and contains 5 to 10% by weight to improve the cohesive force of the filler 310 to increase the cohesive force between particles, and the coated It prevents cracking or dropping of filler material, and it can also supply nutrients necessary for plants and soil.

The soil layer forming step (S40) is a process of forming the soil layer 400 by filling and compacting the soil into the soil filling space 170 . In a state in which the upper cover 150 is opened and the front cover 110 is closed, the soil is filled in the "┌"-shaped soil filling space 170, and then arranged at an angle so that the soil is uniformly filled. Since the rock layer 300 and the filler 310 have already been constructed, it is prevented that the soil layer 400 is subsided by flowing out to the lower side.

The cover soil layer forming step (S50) is a process of forming the cover soil layer 450 by covering the topsoil obtained in the slope preparation and topsoil obtaining step (S10) on the soil layer 400 . After the topsoil is filled in the soil filling space 170 remaining after the soil layer 400 is formed, the topsoil is arranged at an angle so that the topsoil is uniformly filled. The topsoil generated during the slope cleanup work is soil that not only contains grass and leaves grown in the existing topsoil as it is, but also contains abundant organic matter and nutrients necessary for plant growth. 400) If the above is covered with a predetermined thickness, even if no separate compost is used, in addition to artificially planted plant seeds, it is adapted to the local topsoil and naturally included grass grows well, thereby increasing the plant greening effect, and thereafter, organic matter by microorganisms in the topsoil By decomposing this and performing compost function, it provides nutrients lacking in general soil and soil to plants, has excellent moisture and nutrient retention, and promotes plant growth, which can greatly help in ecological restoration. If the topsoil is mixed with the soil layer 400 or included deeply inside the soil layer 400, the above-mentioned effect may be diluted away from the surface layer, and a space is formed inside the soil layer when the organic matter contained in the topsoil is decomposed. The structure may sink.

Here, the thickness of the cover layer 450 is preferably 1/5 to 1/2 of the thickness of the soil layer 400. If it is less than 1/5, the effect of greening vegetation may be reduced, and if it is more than 1/2, the deep If it is included to the depth, there is a problem that the structure may sink or be damaged when the organic matter contained in the topsoil is decomposed.

The seed sowing step (S50) is a process of sowing plant seeds on the front and upper portions of the soil layer 400 in a state in which the front cover 110 is opened, and after installing the econet 600 thereon, the front cover 110 ) and the upper cover 150 is closed to finish.
